IMPRVEMENT IN CURTAIN'FIXTURES.

Specification forming part of Letters Patent No. 160,718, dated March 9, 1875; application filed October 13, 1874.

To all whom it may concern:

Be it known that I, CHARLES P. Rosa, of Allentown, :in the county of Lehigh and in the State of Pennsylvania, have invented certain new and useful Improvements in Shade- Fixtures; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of a curtainfixture, asrwill be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a front view of a window-frame with my curtain-fixture. Fig.2 isa side view of thesame. Figs. 3, 4, 5, o', and 7 are detached sections of the Xture.

A represents an ordinary curtain-roller, provided at one end with a headed pin, a. In the other end of the roller is made a circular recess or hole, for the insertion of a hollow cylinder, B, which is formed with a circumerentially-grooved pulley, C, on its outer end. The cylinder B, with its pulley, is bisected longitudinally, forming two equal halves, and in the outer side of the pulley is a central annular recess, through which projects the end of a spindle, D, placed longitudinally in the cylinder B, and having its bearings at x w x therein. 0n the inner side of the pulley C the cylinder B is enlarged, forming a hollow hub, b, with an interior straight side, b', as shown in Fig. 5. Within this hub the spindle D is formed with straight sides, to make shoulders y. d represents a curved arm, formed with a hook at one end, and fastened in the hollow hub b by a pin, j', passing through an elongated slot, e, at its other end. The outer side of the hooked end of the curved arm d is made beveled or wedge-shaped, so that when the hook is caught by either ofthe shoulders y on the spindle D, and drawn over, it will wedge between said spindle and the straight side b within the hub. E represents the curtain fastened to the roller A, and provided at its lower end with a bar or slat, G, t0 which is fastened a metal bar, h, as shown in Fig. 6. 'm is the curtain-cord, fastened at one end to the roller G, and the other end hanging down loose. The curtain is supported in two brackets, H H', the bracket H being constructed with a square or rectangular opening for the insertion of the correspondinglyshaped end ofthe spindle D, and the bracket H provided with a slot for the headed pin a to drop into.

By the bracket H the spindle D is held stationary, while the cylinder B, with its pulley, revolves around it, the cylinder being fastened in the roller A by a pin, n, as shown in Figs. 3 and 4, and also by dotted lines in Fig. l.

The operation of my curtain-fixture is substantially as follows: The curtain being down, the cord m is wound upon the pulley U 5 then, by pulling on the cord, the roller is revolved, winding up the curtain. During the revolution of the roller the hook-arm d, when it is above the spindle, falls down thereon, and

while the curtain is going up has no effect on the spindle; but when the curtain is lowered' slowly, the hook will once during each revolution catch on one of the shoulders y, and be pulled or drawn along, while the roller and cylinder continue to turn, the length of the slot e in the arm, so that the hook end of said arm will he wedged by the part b of the hub b, thereby stopping the revolution of the roller, and holding the curtain at that point.

To lower the curtain again, it must first be pulled up a short distance, and then let down suddenly, when the weighted slat Gr in the lower end of the curtain will overcome the tendency of the hooked arm cl to catch on the shoulder y, and allow the curtain to descend.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In combination with the weighted curtain E and curtain-roller A, the bisected cylinder B, having hub b, with interior straight side b', and pulley C, the slotted sliding curved hook d, and stationary shaft D, with shoulders y, all constructed substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 18th day of September, 1874.
